Features: MP2234 High-Efficiency, 2A, 16V, 800kHz Synchronous, Step-Down Converter DESCR IPTION The MP2234 is a high-frequency, synchronous, rectified, step-down, swit ch-mode converter with built-in power M OSFETs. It offers a very compact soluti on to achieve a 2A continuous output cu rrent with excellent load and line regu lation over a wide input supply range. The MP2234 has synchronous mode operati on for higher efficiency over the outpu t current load range. Current-mode oper ation provides fast transient response and eases loop stabilization. Full prot ection features include over-current pr otection and thermal shut down. The MP2 234 requires a minimal number of readil y-available standard external component s, and is available in a space-saving 8 -pin TSOT23 package. TYPICAL APPLICATIO N FEATURES  Wide 4.5V-to-16V Operat ing Input Range  100mΩ/40mΩ Low RD S(ON) Internal Power MOSFETs  High-E fficiency Synchronous Mode Operation Fixed 800kHz Switching Frequency  Synchronizes from a 300kHz-to-2MHz E.

MP2234
High-Efficiency, 2A, 16V, 800kHz
Synchronous, Step-Down Converter
DESCRIPTION
The MP2234 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter
with built-in power MOSFETs. It offers a very
compact solution to achieve a 2A continuous
output current with excellent load and line
regulation over a wide input supply range. The
MP2234 has synchronous mode operation for
higher efficiency over the output current load
range.
Current-mode operation provides fast transient
response and eases loop stabilization.
Full protection features include over-current
protection and thermal shut down.
The MP2234 requires a minimal number of
readily-available standard external components,
and is available in a space-saving 8-pin
TSOT23 package.
